Periampullary carcinoma is a malignancy that appears around the vatteri ampulla. This malignancy can originate from the pancreas, duodenum, and distal choledochal duct. Duodenal cancer is a very rare case, only about 0.3% of the gastrointestinal malignancies. Reported cases are increasing with the increasing use of esophagogastroduodenoscopy. The most frequently found carcinomas of the duodenum include adenocarcinoma, carcinoid, lymphoma, and leiomyosarcoma. The symptoms of these carcinomas are often not specific so the diagnosis is often late, leading to a poor prognosis. Early diagnosis and proper therapy provide a good prognosis.  The case reported here representeda 52-year-old woman presented with hematemesis melena, anemia, jaundice, epigastric mass, right hypochondrial pain, and weight loss.
